Application filed March 27, 1906. Serial Il'o. 308,291.

To all-whom it may concern:

Be it known that 1, WILLIAM F. Coon, a citizen of the United States,residin at Louisville, in the county of Jefferson. an State of Kentucky,have invented certain new and useful Improvements in Strainers, of whichthe following is a specification.

This invention provides a strainer of novel construction which isadapted for use in wells, filtration plants, and wherever foreignmatter, such as sand and gravel, is to be separated from water.

The invention consists of a strainer which may be flat, arched,cylindrical or other form an which is composed of parallel bars, rods,or like elements connected by binding-strips, which constitute stayingor bracing means.

For a full descriptionof the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand aceom anyingdrawings.

hile the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essentiai features thereof, still the preferred embodiment isshown in the accompanying drawings, in which Figure I is a perspectiveView of a strainer of flattened form. Fig; 2 is a pore ective view of astrainer of arched form. 3 is an end view of a strainer of cylindricaform having the bars or rods connected and braced by inner and outercircular Fig. 4 is a-perspective view of a cylindrical form of strainerhaving the bars or rods connected by inner and outer circular and spiralstrips. Fi 5 is a detail view showing some of the di erent forms of barsor rods.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views 0 the drawings by the samreference characters.

The strainer may be formed of any material, metal being preferred, thatselected being or a nature not aflected b moisture, such as brass,copper, or zinc. e bars or zoidal, or other form in cross-section,as'indisated most clearly in Fig. 5. The bars or rods 1 are spaced aparta short distance, the interspacin being determined by the particularservice or which the strainer is desi ed. Strips 2 and 3 connect thebars or rods in serice and are arranged in pairs upon opposite sidesthereof. One of the stu s, as 2, is 'transsersely curved between its onitudinal edges and is provided at interva s in its len th with openings4, through which solder is sowed for connecting the strips to each otherand to the bars or rods.

The strainer may be employed for separating' foreign matter, such assand and gravel,-

from water, and when mud or like impurity is tohe separatedfrom thewater the screen is used in the capacity of a support for sus teiningfilterin material such as commonly employed for e iminating impuritiesheld in sus ension in'the water.

he screen may beiiat, as shown in Fig. 1, or curved or arched, asindicated in Fig. 2, or supplied in cylindrical form, as shown in Fi s.3 and 4. In the form shown in Figs. 3 an 4 the inner and outerconnecting means may consist of circular hands, or the strips may have as iral arrangement, as indicated in Fig. 4, t e end portions beingcircular. in the construction shown in Fig. 4 the ends of the bars orrods are connected a uniform distance from their extremities and arebraced and straight at intervals in their length by the spiral arranement of the strips.

Having thus described the invention, is claimed as new is- A strainercomposed of a series of bars or elements having a parallel arrangementand spaced apart a distance, pairs of terminal strips connecting thebars in series and bracing the same, and other pairs of stripsconnecting the bars and arranged between the terminal strips in a spiralor diagonal direction.
